This invention relates to improvements in industrial cars, such as mine cars and quarry cars.

In its broadest aspect, the invention seeks to provide a mine car or other type of industrial car having a maximum volume content while keeping the car within certain limits so far as its over-all dimensions are concerned. For instance, in mining operations,

a car must not exceed a certain height and it is also limited as to width. There must also be a certain amount of clearance between the tracks on which it runs and the bottom of the car. In view of these limitations, the invention has for some of its objects, a car wherein the plates or other members constituting the car bottom are themselves located as near the tracks as possible so as to ain the maximum depth within a limited ei ht and wherein, the Various supporting an reinforcing elements for the car bottom and sides are all located within the car itself. This not only adds to the depth of the body but also results in an increase of the width of the body while still maintaining necessary clearances at the sides.

A further object of the invention is the provision of a novel form of wheel truck that will permit the car bottom to be located as near as possible to the track.

With these and other objects in view, the invention consists in certain novel details 'of construction and combinations and arrangements of parts all as will hereinafter be more fully described and the novel-features thereof particularly pointed out in the appended cla1ms..

In the accompanying drawings: Fi re 1 is a side elevation of a car embodymg the present improvements;

Fig. 2 is a transverse section on the line 22 of Fig. 1;-

Fig. 3 is a longitudinal section on the line 3-3 of Fig. 2; 1

Fig. 4 is an end view of one of the wheel trucks;

Fig. 5 is a side view, partly in section of the truck; Fig. 6 is a section taken axially through one 4 ,of the wheels; and i Fig;e7 is a detail view of the draft gear cham r.

In accordance with the present invention, the car body is mounted on trucks located at opposite ends of the body. .In this way, the central longitudinal portion of the body may be made of a considerably greater depth; it only bein re uired that the end portions of the bod e e evated to accommodate the trucks. owever,

these end portions are of a maximum depth in the present instance,

byv reason of the fact that the bottoms of said ends are located well below the upper peripheral portions of the wheels. To obtain these results, which give a maximum capacity to a car of limited over-all dimensions, a novel form of truck and wheel mounting are provided and, in conjunction therewith, a novel body construction. is utilized in that there are no projecting elements on the sides and bottom of the car. All of these several features serve jointly with one another to gain the desired result, i. e., maximum capacity.

In the preferred construction illustrated, the car body consists essentially of a central longitudinally extending late member 10 properly reinforced to wit tand strains or stresses imposed thereon by reason of the fact that the remainder of the car body is supported therefrom. As shown in Figs. 1 to 3, this plate 10 is reinforced on each side by longitudinal angle irons 11 and lon 'tudi-.

nally spaced, vertically disposed ang es 12. Secured to each an le 12 is a gusset plate 13 to which is fastened a horizontal, transversely extending angle 14. Secured to the outer ends of the several an les 14 are gusset plates 15 and secured to said gussets are vertically disposed angles 16. The plates constituting the bottom 17 of the body are secured to the angles 14 and secured to the vertical angles 16 are the plates constituting the sides 18 of the car. To further strengthen the construction, angles 'I9 are placed in thejunction oints or corners between the bottom and sides, and the upper edges of the sides are rolled inwardly as at 20.-

For accommodation of the draftgear, ofiset channel members 21 are secured to opposite sides of each end of plate 10, the space between each pair of channels being covered by a plate 22 to form a housing for said gear. As before mentioned, the end portion of the car bottom is slightly elevated. Consequently, the plate 10 is of reduced height or depth at these points as shown in Fig. 3. The end portions of the car bottom are also provided at their sides with wheel housings 23 for accommodation of the wheels because, as will later appear, the car bottom between these housings is located in a plane below the upper peripheral portions of the wheels.

On the under surface of the car bottom, at each end, there is a center plate 24 adapted to be suitably mounted on a wheel truck. Preferably, these trucks are so constructed that the central portions of the car bottom, at the ends, will be as low as possible so thatthe depending portion of the bottom between the ends will be as close to the ground or tracks as possible, allowing for necessary clearances beneath the car. To this end, each truck comprises a pair of transverse bolster beams 25 on which the center plate is supported. At their ends, these bolster beams 25 are secured between the side members of the truck, said side members preferably taking the form of an I-beam 26 above the bolsters and a tie bar 27 below. Mounted between side members 26, 27 are the axle boxes for wheel axles 28. These boxes are composed of sections 29a, 296 secured together by bolts 30, the interior of the boxes being large enough to accommodate nuts 32 screwed on the ends of the axles 28. For each wheel 33, there is mounted on the axles a pair of raceways 34a, 34b and each wheel is provided with raceways 35a, 352'), the cooperatingv raceways having interposed between them, anti-friction elements 36. Sur

' rounding the axles and abutting the raceways 340 are annular members 37 which are, in turn, engaged by split sleeves 38 surrounding the axles at points between the axle box sections. Annular member 37, is locked in position relative to split sleeve 38, by square key 39 said key engages slot in annular member and slot in split sleeve. The object of said key being to eliminate any possibility of member 37 rotating on axle 28 while car is in motion. With such a construction, the bearings for the wheels are readily adjustable by the nuts 32 on the axles during assembly of the truck. That is, before the axle box below the upper peripheral portions of the wheels and the central portion of the car quite close to the tracks. Also, to obtain necessary clearance beneath the car, it will be noted that there are no projecting elements on the exterior surface of the body as all the stiffening members are mounted on the interior. Therefore, in a car of limited overall dimensions, a maximum volume capacity is obtained.
